(A) In order to carry out the provisions of this subchapter, there are created and established certain zones which include all of the land lying beneath the approach surfaces, transitional surfaces, horizontal surface and conical surface as they apply to the airport. Such surfaces are shown on the Airspace Drawing, which is made a part hereof. An area located in more than one of the following zones is considered to be only in the zone with the more restrictive height limitation.
(B) The various zones are established and defined as follows:
(1) Approach zones. Approach zones are established beneath the approach surfaces of both ends of Runway 17-35 at the airport for a larger than utility runway with ultimate nonprecision instrument landings and takeoffs. Each approach zone shall have an inner edge width of 500 feet, which coincides with the width of the primary surface at a distance of 200 feet beyond each end of the runway, widening thereafter uniformly to a width of 3,500 feet at a horizontal distance of 10,000 feet beyond each end of the primary surface. The centerline of the approach zones are the continuation of the centerline of the runway.
(2) Conical zone. A conical zone is established beneath the conical surface at the airport which exceeds outward from the periphery of the horizontal surface for a horizontal distance of 4,000 feet.
(3) Horizontal zone. A horizontal zone is established beneath the horizontal surface at the airport which is a plane 150 feet above the established airport elevation, the perimeter of which is constructed by swinging arcs of 10,000 feet radii from the center of each end of the primary surface and connecting the adjacent arcs by lines tangent to those arcs.
(4) Transitional zones. Transitional zones are established beneath the transitional surfaces at the airport. Transitional surfaces, symmetrically located on either side of the runway, have variable widths as shown on the Airspace Drawing. Transitional surfaces extend outward at right angles from the runway centerline and the runway centerline extended from the periphery of the primary surface and the approach surfaces to where they intersect the horizontal surface.
